Eye wash installation knowledge

1. Installation Requirements

According to the ANSI Z358.1-2004 American eye wash standard, the installation of eyewash stations and emergency showers must follow the manufacturer's guidelines and safety regulations. Proper placement and maintenance are essential for effective emergency response in case of chemical exposure.

1.1. Eyewash and shower equipment should be installed close to the potential hazard area. Ideally, it should be accessible within 10 seconds to ensure quick response. It is recommended to install them on the same level and in a straight line to avoid delays during emergencies.

1.2. The location of the equipment should be clearly marked with visible signs. These signs should include both Chinese and English language instructions along with pictograms to help workers quickly identify the location and usage of the equipment during an emergency.

1.3. All components of the eyewash and shower system must comply with the ANSI Z358.1-2004 standard. Each nozzle should be operable independently. In colder regions, anti-freeze devices or heating systems should be installed to prevent freezing and ensure functionality in winter conditions.

When installing the components of the eyewash and shower system, the following additional requirements must also be met:

a. Once connected to the water source and all valves are closed, there should be no leakage from the piping system.

b. When the operating switch is fully open, all valves should remain in the normal open position, unless manually operated by a user.

c. All switches and parts of the equipment should function properly when in full operation, meeting all ANSI Z358.1-2004 standards.

2. Location Requirements for Eyewash and Shower Equipment

2.1. The eyewash and shower equipment should be placed as close as possible to the source of danger. Ideally, employees should be able to reach the unit within 10 seconds. It’s best to install them on the same floor and in a direct path to minimize response time and avoid further injury.

2.2. In special environments where strong acids, alkalis, or other hazardous substances are present, the equipment must be installed as close to the hazard as possible. This ensures immediate access in case of accidental exposure.

2.3. In laboratories where toxic chemicals are handled, eyewash and shower units are typically installed in central locations. However, if workstations are far from the unit, it may delay emergency response. To address this, it is recommended to install a flexible eyewash hose near the lab sink. This allows for quicker access and better protection when chemicals splash onto the face or eyes.
